Topic: Problema SMART

[FrancescoC]

Qualche giorno fa mi sono accorto che il disco sda del mio SME 7.5.1 in raid 1 era stato rimosso dal raid e perciò l'ho riagganciato e lui si è risincronizzato. Ma continuo  ad avere questo log :

E' il caso che sostituisco un disco ? Quale ?

[Stefano]

si
sda

[FrancescoC]

Aggiungo che analizzando i dischi con il cd di diagnostica dell'Hp , perchè si tratta di un Proliant ml 110 g6 , mi dice che tutto è a posto. Chi ha ragione ?

[Stefano]

i tuoi dati comandano...

Code: [Select]

/dev/sda, 3 Offline uncorrectable sectors

se ti si corrompono i dati, la corruzione verrà passata (non in termini di danno fisico al disco ovviamente) anche sul disco sano..

il costo di un disco certamente non vale i miei dati.. i tuoi?

[FrancescoC]

Hai perfettamente ragione !!!!
Ma sono un po' di coccio ....    Quindi è normale che sda lanciando un  smartctl -a /dev/sda

io vedo che sda ha degli errori "read failure"..

sono 2 hd da 250 Gb, quindi hanno un po' di tempo, quasi certamente sono fuori garanzia..

2 serial ata di dimensione maggiore (occhio a non prendere quelli green) e li sostituisci entrambi.. un paio di centinaia di euro (ma anche meno) e vivi felice..

non male, direi

[FrancescoC]

Ok grazie mille !!!
Inizierò a sostituire sda per primo.

@Stefano

Come mai i green no?

[Stefano]

perchè i green hanno delle features che non sono adatte ad un uso continuato h24 in un server ed in raid..
google (sempre da quella parte ---> ) saprà illuminarti

[FrancescoC]

Rieccomi  per dirvi che ho cambiato sda e poi ho risincronizzato il raid . Poi ho ricevuto questa mail :

SMART error (ErrorCount) detected on host: server2010

This email was generated by the smartd daemon running on:

   host name: server2010
  DNS domain: test.local
  NIS domain: (none)

The following warning/error was logged by the smartd daemon:

Device: /dev/sdb, ATA error count increased from 1097 to 1098

For details see host's SYSLOG (default: /var/log/messages).

You can also use the smartctl utility for further investigation.
Another email message will be sent in 1 days if the problem persists

e quindi ho cambiato anche sdb e poi ho risincronizzato il raid.
Ma ancora sui log ho questo :

Possibile? Che devo fare ? 

[Stefano]

dovresti "impratichirti" di più con smartctl per comprendere quali sono i segnali "seri" e quali quelli di "rumore di fondo"

google è il punto da cui partire, magari inserendo come key i vari "Hardware_ECC_Recovered" ecc

[FrancescoC]

Scusa ma non potrebbe essere che mi sono portato dietro degli errori logici dai dischi precendeti e magari con uno "scandisk" di linux posso risolvere?

[Stefano]

no, quelli che vedi non sono errori logici ma variazioni di stato di grandezze dell'hd.. sul come interpretarli devi impararlo tramite google
